As others above, yes the 357 Magnum it is an acceptable cartridge for pigs and other game for that matter.
I have used one with no problems on the receiving end.
I have a Rossi which is light weight and points well.
Trajectory is not your friend here but that's not the point of using 357 Magnum in a lever.
Commercial loads will primarily be self defence offerings but should do ok on game.
My current loading is Speer GDHP's. The 125g are listed as self defence. The 158g are noted for hunting.
Speer doesn’t list any velocity recommendations.

The fun value of 38 Special from a rifle is pretty satisfying.
My take here is the 357 Mag/38 Sp is an upscale 22LR.
